The measured effective thermal conductivities and effective thermal diffusivities of nanofluids were found to be higher than those of base fluids and they increase significantly with increasing volume fraction of nanoparticles. The increments of the thermal diffusivities were found to be slightly larger compared to the thermal conductivity values. For example, at 5% volumetric loading of TiO2 nanoparticles of 15 nm and 10 \u00d7 40 nm in ethylene glycol, the maximum increase in effective thermal conductivity was found to be 17% and 20%, whereas the maximum increase in effective thermal diffusivity was 25% and 29%, respectively. Besides particle volume fraction, particle material, particle size and the nature of the base fluid were found to have influence on the effective thermal conductivity and diffusivity of nanofluids. Based on the calibration results obtained for the base fluids the measurement error was estimated to be within 1.2 to 2%.<\/jats:p>","DOI":"10.1115\/mnht2008-52200","type":"proceedings-article","created":{"date-parts":[[2009,6,23]],"date-time":"2009-06-23T22:33:56Z","timestamp":1245796436000},"page":"549-553","update-policy":"http:\/\/dx.doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":0,"title":["Simultaneous Measurement of the Effective Thermal Conductivity and Effective Thermal Diffusivity of Nanofluids"],"prefix":"10.1115","author":[{"given":"S.
